Tlillan-Tlapallan [ˈt͡ɬilːan t͡ɬaˈpalːan] 'Place of the black and red colour' is a legendary place or region on the Gulf Coast of Mexico where king Quetzalcoatl went on his flight from Tollan in order to burn himself and change into the Morning Star.^[1]

The tale can be found in an important 16th-century manuscript (the Codex Chimalpopoca) containing the Annals of Quauhtitlan. Written in Nahua, the text basically translates a pre-Spanish book. The tale also occurs in Bernardino de Sahagún's General History of the Things of New Spain. The name "Tlillan-Tlapallan" has been interpreted as referring to writing and books.
